Periodontitis is an inflammatory change of the periodontium in which all associated diseases and symptoms weaken the immune system and especially the cellular defence.
For the treatment and prevention of periodontal disease, non-surgical periodontal therapy, such as regular and thorough cleaning of the teeth and interdental spaces, is predominantly used.
It should be noted that supragingival cleaning is not sufficient as the sole periodontal therapy. Only subgingival instrumentation (curettage) brings about a fundamental change in the microbial flora. Special attention is paid to the efficiency of plaque removal. If live bacteria remain in the niches, reinfection occurs rapidly. The aim of the non-surgical therapy is to reduce pockets (probing depths) and signs of inflammation (bleeding).
Prophylaxis, non-surgical pocket therapy and its flanking measures serve as the first steps in the prevention and treatment of periodontal disease.
